BRICK-MOLD.

SPECIFICATION forming part of Letters Patent No. 669,885, dated March 12, 1901.

T0 at whom it may concern:

Be it known that I, SAVILLIAN AeUsrUs WINCHESTER, a citizen of the United States, residing at Council Bluffs, in the county of Pottawattamie and State of Iowa, have invented certain new and useful Improvements in Brick-Molds; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

My invention relates to brick-molds; an its object is to provide a mold of this character with a removable bottom and means for detachably securing the mold thereto.

The invention comprises a framework or mold proper, a base or bottom, and improved means for detachably connecting the mold and its base or bottom board.

The construction of the improvement will be fully described hereinafter in connection with the accompanying drawings, which form a part of this specification, and its novel features will be defined in the appended claims.

In the drawings, Figure l is a view in perspective of a metallic mold embodying the invention and adapted for hand-made brick. Fig. 2 is a longitudinal section of Fig. I. Fig. 3 is a longitudinal section of a modified form of the mold and the device for securing the platform or base thereto, and Fig. 4 is a view in perspective of the clamp or clasp employed for securing the detachable bottom or platform to the mold when employed in molding machine-made bricks.

The reference-numeral 1 designates the bottom board or platform of the mold, preferably provided with parallel cleats or supports 2, located on the under side of the board or platform adjacent to the ends thereof.

The mold proper is of rectangular form and comprises sides 3 and ends 4. The mold is divided by a central vertical longitudinal partition 5 and one or more transverse partitions 6 into spaces or compartments 7 of the size of the brick to be molded. The ends of the sides 3 project beyond the ends 4 of the mold and are formed with openings to receive a bolt 8, threaded at one end to receive a nut 9. The lower edge of each of the ends 4 of the mold is formed with a groove 10 to receive the loops ll of two coil-springs l2 and 13, each formed with a bail, (designated by the numerals I4 and 15.) The bail 14 serves as a handle and the depending bail 15 serves as a clamp to engage the end of the base or platform 1, as best shown in Fig. .2.

Instead of dividing the interior of the mold by a central partition running parallel with the sides of the mold and transverse partitions arranged at right angles to the central partition, the mold may be divided by a plurality of transverse partitions 16, arranged parallel to the ends of the mold to form spaces or compartments 17 of a width equal to the length of the brick to be formed.

In employing the invention in connection with machinemade bricks I dispense with the coilsprings and employ in lieu thereof a spring-clamp at each end of the mold, the construction of said clamp being illustrated in Fig. 4 and comprising a strip of resilient metal bent at one end to form an eye 18 and curved or bent to form a clamp 19. The bolts 8 pass through the eyes 18 of the spring-clamps and support the latter in the proper position to engage the ends of the platform or base 1.

The sides, ends, and partitions constituting the mold proper are cast integral from copper, brass, aluminium, steel, iron, or other suitable metal, and the mold Will be solid without joints or seams.

Crude petroleum or other oil is used to lubricate the mold in lieu of sand, which gives the brick a smooth surface similar to pressed brick and a finish which is much superior to bricks molded in the ordinary mold. An important advantage of my improvement is that the metallic molds do not require to be dumped or turned over on the ground, as the mold may be readily lifted.

The further point of advantage is that the improved metallic molds are durable and will not crack, Warp, or shrink by exposure to the elements.

The saving of labor incident to lifting the molds away from the bricks, leaving the latter upon the platform or base, is an appre ciable feature of my improvement.

By removing the bolts 8 the coil-springs 12 and 13 are removed and may be replaced by the spring-clamps. (Shown in Fig. 4:.)

I claim- 1. A metallic brick-mold comprising parallel sides and integral partitions, the ends of said side pieces projecting beyond the ends of said mold, in combination With removable bolts extending through openings in the ends of the sides, springs arranged on the bolts, and a platform or base, the ends of which are adapted to be engaged and held in position by said springs.

2. A metallic brick-mold comprising parallel sides, end pieces, and integral partitions dividing the mold into spaces or compartments, the ends of said sides extending beyond the ends of the mold, and formed with openings; in combination with removable bolts secured in said openings, coil-springs projecting handles.

In testimony whereof I affix my signature in presence of two Witnesses.
